Twitter - Upload has failed

I have encountered an issue with my BB Z10 when trying to upload a photo via Twitter. Whenver I try to share a photo from within the native twitter app, a third party app, or through the share function in the camera/photo viewer app, or from the hub, it always fails. This has been an issue for quite some time for me.

I am running a leaked version of BB10. The version number is 10.1.0.1627.

I have also ensured that my permissions allow for file sharing through Twitter. Finally, FaceBook and other apps have no issues with photo uploads, this appears to be a Twitter specific problem.
